The story of the Lacs des Chéserys

The Chéserys lakes are a series of small glacial lakes on a rocky shelf in the Aiguilles Rouges nature reserve. They sit just below Lac Blanc and offer the same face-to-face view of the Mont Blanc massif, with fewer people.

The reserve was created in 1974 to protect alpine plants and animals. On the way up you have a good chance of seeing ibex, chamois and marmots close to the trail.
